I have put in new taillightsockets and they all work fine...almost. When the socket is out of the lense , lamp thing it lights up and the turn signal is working, but when i put the socket back in, the turn signal wont work/blink
If you cant understand what the hell im talking about, let me know
That is unusual as the car body is the return path (ground) to complete the electric circuit. Are you using a ground wire to test them when out of the car?
If so that tells you that the sockets that the lamps plug into has a bad ground. This could be due to corrosion or a broken (open) electrical path due to failed spot welds.
Unless there are two filaments inside the bulb (such as the 1157) there should be one wire for each filament and you touch a negative wire to the brass shell to ground the bulb and complete the circuit. I suspect the socket in contact with the brass shell is not grounded properly. Generally just the act of taking a tail light assembly apart and cleaning it reestablishes the ground path.
If it were my car (and I couldn't care less about chalk mark restorations) I would run a ten gage wire from the battery negative terminal into the trunk. There I would create a distribution bus and tie both tail light assemblies, the tag light and the gas tank's sending unit to that bus with separate grounding wires. You will be amazed at how bright the light become when you do that.
On the same tract I would run a ten gage wire from the positive post of the alternator to a BOSCH 50 Amp relay and energize that relay by tying the head light power wire to the relay and run a dedicated wire from the relay to each head lamp in the circuit (a relay for the two high beams and a second relay to power the two low beams). The head lamp has a separate grounding lug that should be run directly to the negative terminal of the battery. That will really brighten your head lights.
I would also verify that the three brass flat cables used as grounding straps are in place and touching unpainted metal on the block or transmission bell housing as that is how the car is grounded.
I know they are not cheap, but I had problems with my brake and tail lights for years. I replaced them with LED's and cut the socket plug in 's off and wired them direct. I haven't touched them in over 3 years.
